Whether you are building a new modern sporting rifle, or filling your spare parts kit, you need a good quality bolt carrier group. This is a "full auto" profile bolt carrier group that is slightly heavier than a "semi auto" bolt. This benefits shorter carbine length gas systems and suppressed firearms. Both carrier types are interchangeable and there is no restriction on the ownership of a "full auto" BCG in a semi automatic gun. These bolt carrier groups are manufactured for Wilson Combat by some of the finest Mil-Spec contractors, and are easily among the best 5.56 AR rifle bolts on the market. They are precisely machined, finished and hardened to ensure long term reliable performance.
